Depression Subtypes in Systolic Heart Failure: A Secondary Analysis From a Randomized Controlled Trial. J Acad Consult Liaison Psychiatry 2023; 64:444-456. [PMID: 37001642 PMCID: PMC10523864 DOI: 10.1016/j.jaclp.2023.03.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/26/2022] [Revised: 03/22/2023] [Accepted: 03/24/2023] [Indexed: 03/31/2023]
Abstract
BACKGROUND Heart failure (HF) is associated with an elevated risk of morbidity, mortality, hospitalization, and impaired quality of life. One potential contributor to these poor outcomes is depression. Yet the effectiveness of treatments for depression in patients with HF is mixed, perhaps due to the heterogeneity of depression. METHODS This secondary analysis applied latent class analysis (LCA) to data from a clinical trial to classify patients with systolic HF and comorbid depression into LCA subtypes based on depression symptom severity, and then examined whether these subtypes predicted treatment response and mental and physical health outcomes at 12 months follow-up. RESULTS In LCA of 629 participants (mean age 63.6 ± 12.9; 43% females), we identified 4 depression subtypes: mild (prevalence 53%), moderate (30%), moderately severe (12%), and severe (5%). The mild subtype was characterized primarily by somatic symptoms of depression (e.g., energy loss, sleep disturbance, poor appetite), while the remaining LCA subtypes additionally included nonsomatic symptoms of depression (e.g., depressed mood, anhedonia, worthlessness). At 12 months, LCA subtypes with more severe depressive symptoms reported significantly greater improvements in mental quality of life and depressive symptoms compared to the LCA mild subtype, but the incidence of cardiovascular- and noncardiovascular-related readmissions, and mortality was similar among all subtypes. CONCLUSIONS In patients with depression and systolic heart failure those with the LCA mild depression subtype may not meet full criteria for major depressive disorder, given the overlap between HF and somatic symptoms of depression. We recommend requiring depressed mood or anhedonia as a necessary symptom for major depressive disorder in patients with HF.

Does it matter what is trained? A randomized controlled trial evaluating the specificity of alpha/delta ratio neurofeedback in reducing tinnitus symptoms. Brain Commun 2023; 5:fcad185. [PMID: 37680692 PMCID: PMC10481778 DOI: 10.1093/braincomms/fcad185] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2022] [Revised: 05/18/2023] [Accepted: 06/22/2023] [Indexed: 09/09/2023] Open
Abstract
Previous studies showed that alpha/delta ratio neurofeedback was effective in reducing unpleasant psychological, emotional and perceptual consequences of tinnitus. The main goal of the present study was to investigate, whether the specific combination of enhancing alpha frequency band activity and reducing delta frequency band activity was necessary, or merely sufficient, to obtain a positive treatment outcome regarding tinnitus distress and intensity. A second research aim was to assess the relative contribution of neurofeedback-related non-specific and general non-specific effects in neurofeedback treatment. In a three-arm, randomized controlled trial, 94 chronic tinnitus patients were randomly assigned to one of three conditions: alpha/delta ratio neurofeedback (n = 31), beta/theta ratio neurofeedback (n = 28) and non-neurofeedback minimal treatment intervention (n = 35). Neurofeedback participants underwent 10 treatment sessions over a 4-week period. Outcome measures were collected pre-, mid- and post-interventions and at 3-months follow-up. The Tinnitus Handicap Inventory and the Tinnitus Magnitude Index were used as primary outcome measures for tinnitus distress and tinnitus intensity. EEG data recorded during training supplemented primary outcomes. Since data were repeated measures, the analyses used a two-level mixed effects model approach including by-subject random effects (random intercept). For the Tinnitus Handicap Inventory, the results showed no interaction effect. For the Tinnitus Magnitude Index, the analysis showed a significant time × group interaction, indicating that both alpha/delta ratio neurofeedback and beta/theta ratio neurofeedback reported reduced tinnitus intensity. Analysis of EEG data showed a consistent pattern for the alpha/delta ratio over the course of training. Compared to beta/theta ratio neurofeedback, alpha/delta ratio neurofeedback showed an elevated response. Conversely, for the beta ratio to theta ratio, the pattern was more inconsistent, with no clear indication of superiority for beta/theta ratio neurofeedback over alpha/delta ratio neurofeedback. The main question of this piece of research was whether alpha/delta ratio neurofeedback demonstrated frequency band specificity in the alleviation of tinnitus distress and perceived intensity. Results showed that alpha/delta ratio neurofeedback was sufficient but importantly 'not' necessary to achieve a positive outcome on both the Tinnitus Handicap Inventory and Tinnitus Magnitude Index, when compared to beta/theta ratio neurofeedback. Still, the data suggest a trend towards specificity for alpha/delta ratio neurofeedback. Because of this, it may be too premature to discard alpha/delta ratio neurofeedback in the treatment of tinnitus. Recommendations for future studies are outlined.

Abstract
<b><i>Ziel:</i></b> Die vorliegende Studie beschreibt die Evaluation eines universitären Bachelorkurses zur Diagnostik psychischer Störungen im Kindes- und Jugendalter hinsichtlich der erworbenen Fähigkeiten von Studierenden bei Anwendung eines strukturierten Interviews (Kinder-DIPS-OA). <b><i>Methode:</i></b> Zweiundfünfzig Psychologiestudierende nahmen an der Evaluation des Kurses teil. Die Inhalte stellten eine verkürzte Form des standardisierten Trainings zum Kinder-DIPS-OA dar. Am Ende des Kurses bestimmten wir die prozentuale Übereinstimmung der ICD-10-Diagnosen der Studierenden nach Rezeption eines Interviews auf Video mit der vorher festgelegten Diagnose der Seminarleitung. Für ein simuliertes Interview wurden Fehlerquellen und Schwächen der Studierenden in der eigenständigen Interviewdurchführung durch die Seminarleitung nach vorher festgelegten Fehlerquellen prozentual kodiert. <b><i>Ergebnisse:</i></b> Alle Studierenden kodierten die primäre Störung korrekt, aber 84,7% übersahen die komorbide Symptomatik. Nur 11,5% der Studierenden identifizierten die richtige Kombinationsdiagnose nach ICD-10. Die Hauptschwierigkeiten bei der Durchführung des Interviews bestanden darin, die Kriterien angemessen zu explorieren und eine klinische Bewertung auf der Grundlage der Antworten der Befragten vorzunehmen. <b><i>Schlussfolgerungen:</i></b> Im Rahmen des Kurses gelang es, die Studierenden im Kinder-DIPS-OA so weit zu schulen, dass sie auf der Grundlage eines technisch einwandfreien Interviews reliable Diagnosen stellen konnten. Allerdings traten bei der praktischen Durchführung typische Schwierigkeiten auf, die die Reliabilität und Validität der Diagnosen gefährdeten. Um die Studierenden besser auf die klinisch-diagnostische Praxis nach dem neuen, zur Approbation führenden Master vorzubereiten, muss die universitäre Lehre hier nachbessern und stärker praxisorientierte Lehrkonzepte etablieren.

Abstract
INTRODUCTION Research has shown non-trivial base rates of noncredible symptom report and performance in the clinical evaluation of attention-deficit/hyperactivity disorder (ADHD) in adulthood. The goal of this study is to estimate and replicate base rates of symptom and performance validity test failure in the clinical evaluation of adult ADHD and derive prediction models based on routine clinical measures. METHODS This study reuses data of a previous publication of 196 adults seeking ADHD assessment and replicates the findings on an independent sample of 700 adults recruited in the same referral context. Measures of symptom and performance validity (one SVT, two PVTs) were applied to estimate base rates. Prediction models were developed using machine learning. RESULTS Both samples showed substantial rates of noncredible symptom report (one SVT failure: 35.7% - 36.6%), noncredible test performance (one PVT failure: 32.1% - 49.3%; two PVT failures: 18.9% - 27.3%), or both (each one SVT and PVT failure: 13.3% - 22.4%; one SVT and two PVT failures: 9.7% - 13.7%). Machine learning algorithms resulted in generally moderate to weak prediction models, with advantages of the reused sample compared to the independent replication sample. Associations between measures of symptom and performance validity were negligible to small. CONCLUSIONS This study highlights the necessity to include measures of symptom and performance validity in the clinical evaluation of adult ADHD. Further, this study demonstrates the difficulty to characterize the group failing symptom or performance validity assessment.

Self-management training vs. neurofeedback interventions for attention deficit hyperactivity disorder: Results of a randomized controlled treatment study. Front Psychiatry 2022; 13:969351. [PMID: 36061275 PMCID: PMC9433654 DOI: 10.3389/fpsyt.2022.969351] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Accepted: 07/22/2022] [Indexed: 11/13/2022] Open
Abstract
OBJECTIVES Neurofeedback (NF) and self-management training (SMT) may be viable treatment options for patients with attention deficit hyperactivity disorder (ADHD) if they alleviate core symptoms, enhance the patients' self-concept and improve their quality of life (QoL). Aim of the current study is evaluating both interventions accordingly and to test whether specific improvements in core symptoms lead to more general improvements in self-concept and QoL. METHODS In a psychotherapeutic outpatient clinic in Germany, a total of N = 139 children with ADHD were screened for eligibility, of which 111 fulfilled inclusion criteria and participated in the study in accordance with the CONSORT 2010 statement. These were randomly assigned to NF vs. SMT interventions. Changes from pre- to post-intervention in core ADHD symptoms relying on parent and teacher reports (CONNERS 3) and objective tests (Qb-Test) as well as self-concept (interview with the children) and QoL assessments (using the KINDL-R self-report) were compared between patients receiving NF or SMT. RESULTS Significant improvements in ADHD symptoms were achieved similarly in both treatment groups, whilst QoL and self-concept improved after SMT only. CONCLUSION This treatment study provides further evidence that SMT and NF may reduce core symptoms, but SMT may also improve patients' self-concept and QoL and may thus in its current form be the favorable treatment option in naturalistic settings. However, several limitations of the current study implicate that further research is required before definitive conclusions and recommendations for clinical practice can be given.

Abstract
OBJECTIVE Family history of premature myocardial infarction (FH-MI) increases the risk for coronary heart disease (CHD). Research has shown that this effect cannot be accounted for by increased genetic vulnerability alone. We tested the hypothesis that FH-MI is associated with psychological distress, which is known to increase CHD risk, and that this effect is sustained over years and mediated by personality traits and coping strategies. METHOD Levels of distress (i.e., exhaustion, depression, and anxiety) were compared between patients with versus without FH-MI and those with versus without own history of myocardial infarction (MI) from the large observational Diagnostic trial on Prevalence and Clinical Course of Diastolic Dysfunction and Heart Failure (DIAST-CHF) study of patients with cardiovascular risk factors or manifest heart disease (N = 1,470). RESULTS FH-MI was associated with a range of personality traits and coping strategies and independently predicted psychological distress, whereas own MI did not. In mediation analysis, we found that sociotropy and avoidant coping serially mediated significant portions of the effect of FH-MI on distress. Proportions of explained variance ranged from R2 = .11 for depressive symptoms to R2 = .25 for anxiety. Effects remained stable at 1-year follow-up. Several alternative hypotheses were tested and found to be less well supported by the data. CONCLUSIONS Participants with cardiovascular risk factors and FH-MI report increased distress, even years after the event, which might be one component leading to their increased CHD risk. They should be offered support for dealing with distress and life events recurring on sociotropy and avoidant coping as important diathesis factors.

ADHD overdiagnosis and the role of patient gender among Iranian psychiatrists. BMC Psychiatry 2021; 21:514. [PMID: 34663272 PMCID: PMC8525031 DOI: 10.1186/s12888-021-03525-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/01/2020] [Accepted: 10/05/2021] [Indexed: 11/30/2022] Open
Abstract
BACKGROUND Regarding the controversy about the overdiagnosis of Attention Deficit/Hyperactivity Disorder (ADHD) in children and adolescents there are two main directions addressed as issue of age bias and issue of gender bias. In this relation, replication of findings demonstrating significant overdiagnosis is of importance which make the systematic evaluation of such occurrence necessary. OBJECTIVE The seminal study by Bruchmüller, Margraf & Schneider, 2012 is replicated here, although in a different cultural context, in this case Iran, as ADHS might be perceived differently there. We assessed both gender bias and the impact of potential overdiagnosis on treatment recommendations. METHODS A total of 344 licensed Iranian psychiatrists (mean age = 45.17, SD = 9.50) participated in this study. Each psychiatrist received a cover letter that introduced the study as well as a case vignette. Overall, there are eight different cases, one child with ADHD and three non-ADHD children, for both a boy (Ali) and a girl (Sara). Participants also received a questionnaire requesting their particular diagnosis, treatment recommendation and the therapist's sociodemographic information. Chi square tests and multiple logistic regression were applied for data analyses. RESULTS Overdiagnosis occurred in both girl and boy children, although overdiagnosis was 2.45 more likely in boys than in girls (p < 0.01). With respect to the psychiatrist's gender, we detected no difference between males or females, as both overdiagnosed ADHD in boys (pfemale < 0.01 and pmale < 0.01). Furthermore, ADHD overdiagnosis had a direct impact on medication prescription (p < 0.01). CONCLUSION This study suggests that diagnosticians should strictly adhere to diagnostic criteria to minimize diagnostic error.

Emotions or attention – what are predictors for the development of childhood psychopathology? A longitudinal study with pre- and elementary school children. CURRENT PSYCHOLOGY 2021.

Abstract
AbstractCurrent debate has identified the factors emotion knowledge (EK) and attention as specific trajectories longitudinally influencing psychopathological development in childhood. The “Emotion Knowledge Hypothesis” assumes that children with great emotion skills have high self-regulating abilities that result in lower cognitive load and stronger attention capacities. Attention problems are thus perceived as a consequence of reduced EK. According to the competing “Attention Effect Hypothesis”, attention problems and EK deficits are associated because of impaired learning capacities due to attention problems. According to this hypothesis, attention problems are predictive of impaired EK. If those specific trajectories are disrupted, this might attenuate the development of later behavior problems. The present study tests those competing hypotheses replicating previous studies in this field to shed light on potential psychopathology trajectories. A total of 136 pre- and elementary school children as well as their teachers participated in this study. Children’s symptoms of inattention as well as their emotional competences were assessed 3 times over a 12-month period. We applied multilevel structural equation modelling and cross-lagged panel models for data analysis. Overall, we noted a drop in inattention scores and rise in emotional competences over the one-year course, indicating maturation effects. There was a significant but very small effect for attention scores predicting emotional competences. With respect to the question whether interventions should focus on the “Emotion Knowledge” or “Attention Effect” hypothesis, our findings imply that none of them has superiority over the other. Therefore, both emotion knowledge and attention are crucial for development, and that children with deficits in either domain should receive targeted interventions in order to disrupt potentially harmful developmental pathways.

Abstract
A reliable diagnosis of adult Attention Deficit/Hyperactivity Disorder (ADHD) is challenging as many of the symptoms of ADHD resemble symptoms of other disorders. ADHD is associated with gambling disorder and obesity, showing overlaps of about 20% with each diagnosis. It is important for clinical practice to differentiate between conditions displaying similar symptoms via established diagnostic instruments. Applying the LightGBM algorithm in machine learning, we were able to differentiate subjects with ADHD, obesity, problematic gambling, and a control group using all 26 items of the Conners' Adult ADHD Rating Scales (CAARS-S: S) with a global accuracy of .80; precision (positive predictive value) ranged between .78 (gambling) and .92 (obesity), recall (sensitivity) between .58 for obesity and .87 for ADHD. Models with the best 5 and best 10 items resulted in less satisfactory fits. The CAARS-S seems to be a promising instrument to be applied in clinical practice also for multiclassifying disorders displaying symptoms resembling ADHD.

Neurofeedback for tinnitus: study protocol for a randomised controlled trial assessing the specificity of an alpha/delta neurofeedback training protocol in alleviating both sound perception and psychological distress in a cohort of chronic tinnitus sufferers. Trials 2020; 21:382. [PMID: 32370767 PMCID: PMC7201543 DOI: 10.1186/s13063-020-04309-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2019] [Accepted: 04/02/2020] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Tinnitus is a particularly common condition and can have debilitating psychological consequences for certain people. Although several interventions have been helpful in teaching individuals to better cope with tinnitus, no cure exists at present. Neurofeedback is an emerging treatment modality in tinnitus. Previous studies, utilising an alpha/delta training protocol, have shown promise. However, they were characterised by small sample sizes and a lack of neurofeedback control conditions. Therefore, the aim of this study is to investigate whether an alpha/delta neurofeedback training protocol, compared to beta/theta neurofeedback or a diary control group, is effective in reducing not only the tinnitus sound perception but also the psychological symptoms associated with the condition. METHODS The study is designed as a three-armed randomised controlled trial. Participants are randomly assigned to a) an established neurofeedback protocol for tinnitus (alpha/delta training), b) an active control group (beta/theta training) or c) a diary control group. In the 4-week intervention period, participants in both neurofeedback groups undergo 10 sessions, whereas participants in the diary control group complete a bi-weekly diary. The primary outcomes are between group differences in tinnitus sound perception change, as measured with the Tinnitus Magnitude Index (TMI), and changes in tinnitus distress, measured with the Tinnitus Handicap Inventory (THI), 4 weeks after the start of the intervention. Secondary outcome measures include changes in tinnitus distress, sleep quality, depressive symptoms and whether neurofeedback leads to specific power changes in the trained frequency bands. DISCUSSION This is the first randomised controlled trial examining the efficacy of an alpha/delta neurofeedback training protocol in reducing tinnitus sound perception and the distress associated with the condition. Compared to former studies, the present study is designed to assess both the specificity of an alpha/delta neurofeedback training protocol by including an active comparator and beta/theta neurofeedback training, in addition to controlling for placebo effects by the inclusion of a diary control group. This study aims to contribute to an understanding of the influences of both specific and non-specific effects in neurofeedback treatment for tinnitus.

Abstract
BACKGROUND Emotional symptoms are increasingly considered a core feature of attention deficit/hyperactivity disorder (ADHD). We aimed to quantify the evidence of emotional dysregulation and its respective facets in individuals with adult ADHD compared to healthy controls using meta-analysis. METHODS Two electronic databases (PubMed, PsycINFO) were reviewed to identify studies. Studies were eligible for inclusion that had reports on any measure of emotion (dys) regulation in adults (> 18 years of age) in clinically diagnosed patients with ADHD as well as healthy control participants. We included a total of 13 studies (N = 2535) to assess (1) the standardized mean difference in emotion dysregulation (ED) as a general factor and its specific facets (i.e., emotional lability, negative emotional responses, and emotion recognition) between adults with ADHD and healthy controls; and (2) the association between ADHD symptom severity and ED. RESULTS Compared to healthy controls, adults with ADHD revealed significantly higher levels of general ED (Hedges' g = 1.17, p < 0.001; Hedges' g is the adjusted effect size). With regard to intermediate dimensions of ED, emotional lability exhibited the strongest weighted effect (Hedges' g = 1.20, CI [0.57, 1.83], p < 0.001). Furthermore, symptom severity and general ED correlated significantly (r = 0.54, p < 0.001). Regarding intermediate dimensions of ED, negative emotional responses correlated closely with ADHD symptom severity (r = 0.63, p < 0.001) and emotional lability (r = 0.52, p < 0.001). CONCLUSIONS Our findings support ED symptoms as a core feature of ADHD's psychopathology. With respect to dimensions of ED, emotional lability, and negative emotional responses play a more definitive role in the psychopathology of adults with ADHD. Due to insufficient statistical reports in the included studies, we could not perform meta-regressions to control the role of moderator variables.

Abstract
Hypoparathyroidism patients suffer a variety of complaints often leading to reduced quality of life. Currently, no specific standard instrument exists to measure corresponding disease manifestations. We therefore aimed to develop a disease-characteristic questionnaire for hypoparathyroid patients. We used an analytical-empirical approach for questionnaire construction based on retrospective analysis of four well-established but non-disease-specific questionnaires (Symptom Checklist 90, revised [SCL-90-R]; Giessen Complaint List [GBB]; Short-Form-36 Health Survey [SF-36]; von Zerssen Symptom List [B-L Zerssen]) and two additional unpublished or local questionnaires (SHGdQ and GPQ) in a German hypoparathyroidism self-help group (n = 60). Retrospective data were compared with corresponding general population norms. The new questionnaire was administered prospectively over 1 year to patients with postoperative hypoparathyroidism and two control groups to validate specificity. Exploratory factor analysis (EFA) and reliability testing were applied to identify relevant scales and reduce overlapping items. In the self-help group, SCL-90-R revealed elevated symptom load in four complaint areas (p = 0.003 to p < 0.001). The SF-36 mental summary score (p < 0.001) and further scales were lowered. In the GBB, four of five scales (p = 0.009 to p < 0.001) were elevated. In the B-L Zerssen, 6 of 24 items revealed complaint areas. Based on these findings, the new 40-item "Hypoparathyroid Patient Questionnaire" (HPQ 40) was developed, tested prospectively, and further analyzed. EFA revealed five scales (pain and cramps, gastrointestinal symptoms, depression and anxiety, neurovegetative symptoms, loss of vitality), all with Cronbach's alpha >0.7. The questionnaire was revised accordingly and shortened to 28 questions to avoid redundancy. We present a new disease-characteristic questionnaire for hypoparathyroidism patients. Prospective testing revealed five major complaint areas and promising psychometric properties. This questionnaire can be tested for usefulness in further clinical trials. © 2019 The Authors.

Abstract
Aim: Heart failure negatively impacts quality of life (QoL), which in turn contributes to an adverse long-term prognosis. We aimed at identifying biomarker trajectories after an episode of acutely decompensated heart failure (ADHF) that differ between patients showing average versus impaired QoL 1 year later, thus allowing to predict impaired QoL. Methods: Biomarkers were repeatedly measured throughout the year in 104 ADHF patients. QoL was assessed at discharge and 1 year after ADHF. Logistic regression and receiver operating characteristic analyses were used to identify predictors of impaired QoL while controlling psychosocial confounders. Results: MR-proANP predicted impaired physical and mental QoL. NT-proBNP measurements were important predictors for poor physical QoL. Conclusion: MR-proANP and NT-proBNP predict poor QoL after an epidode of ADHF. The trial is registered at http://clinicaltrials.gov as MOLITOR (IMpact of therapy optimisation On the Level of biomarkers in paTients with Acute and Decompensated ChrOnic HeaRt Failure) with unique identifier: NCT01501981.

Emotion regulation in patients with heart failure: Its relationship with depressive symptoms and rehospitalization. J Psychosom Res 2019; 125:109811.

Abstract
OBJECTIVE To examine the role of emotion regulation and its relationship to mental and physical health in patients with heart failure (HF). METHODS Patients hospitalized with HF were screened for depressive symptoms with the two-item Patient Health Questionnaire (PHQ-2) and classified as screen-positive if endorsing ≥1 item and otherwise as screen-negative. One month after hospital discharge, the Emotion Regulation Questionnaire (ERQ) was administered to assess suppression and reappraisal as emotion regulation strategies. In all participants who completed the ERQ (N = 394), all-cause rehospitalization and depressive symptoms using the PHQ-9 were assessed at 1-, 3-, and 6-months after hospital discharge. RESULTS Overall, PHQ-9 scores decreased by 6-months (-0.13 points/month, p = .003), and although suppression showed a small association with depression, neither strategy modulated the slope of the decline in depressive symptoms. Multivariable-adjusted Cox models showed that reappraisal and suppression were not related to all-cause rehospitalization in the entire cohort. However, increasing reappraisal reduced rehospitalization risk by 24% for screen-positive patients (N = 311, HR = 0.76, p = .02), but increased it by 94% in screen-negative patients (N = 83, HR = 1.94, p = .009). CONCLUSION Suppression and reappraisal showed specific and divergent associations in patients with HF: Suppression may relate to depressive symptoms. Reappraisal was associated with rehospitalization, but differently for patients with a positive vs. negative depression screen. Further studies are needed to examine whether emotion-regulation skill training can improve mental and physical health in depressed patients with HF or ameliorate depression in those at-risk.

Abstract
BACKGROUND Risk factor control is essential in limiting the progression of coronary heart disease, but the necessary active patient involvement is often difficult to realise, especially in patients suffering psychosocial risk factors (e.g. distress). Blended collaborative care has been shown as an effective treatment addition, in which a (non-physician) care manager supports patients in implementing and sustaining lifestyle changes, follows-up on patients, and integrates care across providers, targeting both, somatic and psychosocial risk factors. AIMS The aim of this study was to test the feasibility, acceptance and effect of a six-month blended collaborative care intervention in Germany. METHODS For our randomised controlled pilot study with a crossover design we recruited coronary heart disease patients with ⩾1 insufficiently controlled cardiac risk factors and randomised them to either immediate blended collaborative care intervention (immediate intervention group, n=20) or waiting control (waiting control group, n=20). RESULTS Participation rate in the intervention phase was 67% (n=40), and participants reported high satisfaction (M=1.63, standard deviation=0.69; scale 1 (very high) to 5 (very low)). The number of risk factors decreased significantly from baseline to six months in the immediate intervention group (t(60)=3.07, p=0.003), but not in the waiting control group t(60)=-0.29, p=0.77). Similarly, at the end of their intervention following the six-month waiting period, the waiting control group also showed a significant reduction of risk factors (t(60)=3.88, p<0.001). CONCLUSION This study shows that blended collaborative care can be a feasible, accepted and effective addition to standard medical care in the secondary prevention of coronary heart disease in the German healthcare system.

Motivational interviewing can support physical activity in elderly patients with diastolic heart failure: results from a pilot study. ESC Heart Fail 2019; 6:658-666. [PMID: 30963721 PMCID: PMC6676275 DOI: 10.1002/ehf2.12436] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2018] [Accepted: 02/28/2019] [Indexed: 12/13/2022] Open
Abstract
Aims Patients suffering from heart failure with preserved ejection fraction (HFpEF) report similar symptoms and reduction in quality of life to those with reduced ejection fraction but remain largely untreated. We conducted a preliminary evaluation of the acceptance, feasibility, and efficacy of a motivational interviewing (MI) intervention to support elderly patients suffering from HFpEF in maintaining or starting physical activity. Methods and results At the conclusion of the exercise training in diastolic heart failure parent trial that examined the effects of supervised exercise, patients with HFpEF were offered participation in a two‐group pilot study. Based on their preference, consenting patients were assigned to either a 6 month MI intervention group (n = 19) or their physicians' usual care (n = 20). To support participants in increasing and/or maintaining their physical activity, counsellors delivered a mean of 6.5 MI sessions (face to face and via telephone) and also provided a physical activity diary as self‐management tool. At baseline and 6 months, we assessed participants' physical activity motivation (Sportbezogene Selbstkonkordanz Scale) and their physical improvements with the 6 min walk test and a cardiopulmonary exercise test. Of the entire sample (N = 39), 46% were female, their mean age was 73, 90% were in New York Heart Association Class II, and the mean ejection fraction was 61.4%. The majority of MI participants rated the intervention as acceptable, 90% perceived MI as helpful in setting specific exercise goals and overcoming barriers concerning physical activity, and 58% considered the physical activity diary as very helpful. Three‐quarters of MI participants (79%) reported an increase in their physical activity compared with the previous year. Intervention participants showed a greater increase in median peak VO2 from baseline to 6 months (baseline: 18.4 mL/kg/min; 6 months: 20.4 mL/kg/min) compared with the control group (baseline: 20.0 mL/kg/min; 6 months: 19.2 mL/kg/min; P = 0.015). There was no significant change in motivation on the Sportbezogene Selbstkonkordanz Scale for either group (MI: 1.7 vs. 3, P = 0.55; control: 4.7 vs. 4, P = 0.26) nor did patients show any significant improvements in the 6 min walk test (MI: 549 vs. 540 m, P = 0.80; control: 572 vs. 580 m, P = 0.37). Counsellors rated the implementation of the MI intervention as feasible. Conclusions The results from this pilot study suggest that our MI intervention was well accepted by participants and deemed feasible. It also appears to be an effective treatment to increase and maintain physical activity and exercise capacity in patients suffering from HFpEF. Our findings need to be confirmed in a randomized clinical trial with larger and unselected patient cohorts.

Emotional dysregulation is a primary symptom in adult Attention-Deficit/Hyperactivity Disorder (ADHD). J Affect Disord 2018; 232:41-47. [PMID: 29477097 DOI: 10.1016/j.jad.2018.02.007] [Citation(s) in RCA: 78] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2017] [Revised: 01/17/2018] [Accepted: 02/12/2018] [Indexed: 11/16/2022]
Abstract
BACKGROUND Clinical observations suggest that adults have more diverse deficits than children with Attention Deficit/Hyperactivity Disorder (ADHD). These seem to entail difficulties with emotionality, self-concept and emotion regulation in particular, along with the cardinal symptoms of inattention, impulsivity, and hyperactivity for adult patients. Here, we probed a model that explicitly distinguished positive and negative affect, problems with self-concept and emotion regulation skills as distinct but correlating factors with the symptom domains of inattention, hyperactivity, and impulsivity. METHODS Participants were 213 newly diagnosed adults with ADHD (62.9% male, mean age 33.5 years). Symptoms were assessed via self-report on the Conners' Adult ADHD Rating Scales, a modified version of the Positive and Negative Affect Scale and the Emotion Regulation Skill Questionnaire. A confirmatory factor analysis with the R package lavaan, using a robust Maximum Likelihood estimator (MLR) for non-normal data, was conducted to test our new non-hierarchical 7-factor model. RESULTS All calculated model-fit statistics revealed good model-fit (χ2/df ratio = 2.03, robust RMSEA = .07). The SRMR in our model reached .089, indicating an acceptable model fit. Factor loadings on the postulated factors had salient loadings ≥ .31 except for one item on the hyperactivity factor. Latent factor associations were especially salient between emotional dysregulation and problems with self-concept, and also partially with impulsivity/emotional lability. LIMITATIONS The three models of ADHD and emotion regulation as suggested by Shaw et al. (2014) could not be disentangled in this study, though the overall results support the model with shared neurocognitive deficits. Further, we did not separately analyze ADHD with or without comorbid disorders. As our sample of clinical cases with ADHD is highly comorbid (47.9%), other disorders than ADHD might account for the emotion regulation deficits, though a sensitivity analysis revealed no such differences. CONCLUSIONS Our model adequately characterizes the relations between and among clinically and therapeutically relevant symptoms in adult ADHD, thus potentially informing future therapeutic interventions by targeting the successful and flexible use of adaptive emotion regulation skills.

Elevated Plasma C-Terminal Endothelin-1 Precursor Fragment Concentrations Are Associated with Less Anxiety in Patients with Cardiovascular Risk Factors. Results from the Observational DIAST-CHF Study. PLoS One 2015; 10:e0136739. [PMID: 26322793 PMCID: PMC4556459 DOI: 10.1371/journal.pone.0136739] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2015] [Accepted: 08/07/2015] [Indexed: 01/25/2023] Open
Abstract
Background The role of endothelin-1 (ET-1) in the neurobiology of anxiety is unknown, therefore, we assessed in the observational multicenter DIAST-CHF study whether the C-terminal ET-1 precursor fragment (CT-proET-1) is linked to anxiety. Methods Plasma concentrations of CT-proET-1 were measured in a total of 1,410 patients presenting with cardiovascular risk factors (mean age 66.91±8.2 years, 49.3% males, mean left ventricular ejection fraction 60.0±8.2%) who had completed the Hospital Anxiety and Depression Scale (HADS) questionnaire. Results Among the total study cohort (n = 1,410), there were 118 subjects (8.4%) with an HADS anxiety score above the cut-off level of 11 suggestive of clinically relevant anxiety. Plasma CT-proET-1 levels were significantly lower in the group of anxious patients as compared to non-anxious patients (p = 0.013). In regression models adjusted for sex, age, systolic blood pressure, and diameters of left atrium and ventricle, plasma CT-proET-1 was again linked to anxiety (Exp(β) = 0.247, 95%-confidence interval [95%-CI] = 0.067–0.914, p = 0.036). Given the high prevalence of depressive disorders in anxious patients, we additionally included the HADS depression score as an independent variable in the models and found that CT-proET-1 remained a significant predictor of anxiety, independent of comorbid depression (Exp(β) = 0.114, 95%-CI = 0.023–0.566, p = 0.008). Conclusions Our data from a population-based study in outpatients with cardiovascular risk factors revealed that circulating CT-proET-1 levels are negatively associated with anxiety. Further investigations are required to clarify the putative anxiolytic effect of ET-1 or its precursor molecules in humans and to decipher its mechanistic pathways.

The COMT Val158Met polymorphism regulates the effect of a dopamine antagonist on the feedback-related negativity. Psychophysiology 2014; 51:805-9.

Abstract
Consistent with dopamine accounts of internal and external feedback processing, prior work showed that the dopamine D2 receptor antagonist sulpiride modulates the relationship between the dopaminergic COMT Val158Met polymorphism and the error-related negativity (ERN). Here, we tested in an independent sample whether this Gene × Substance interaction generalizes to the feedback-related negativity (FRN), which presumably shares underlying dopaminergic mechanisms with the ERN. N = 83 female participants genotyped for COMT Val158Met received 200 mg sulpiride versus placebo and performed a virtual ball-catching task. The FRN to positive versus negative feedback was modulated by a significant COMT × Substance interaction. Mirroring prior work on the ERN, the tendency of the FRN to be more pronounced for VAL+ versus MET/MET carriers after placebo was reversed by sulpiride. The findings thus provide new evidence for dopaminergic models of feedback processing.

Paradoxical dopaminergic drug effects in extraversion: dose- and time-dependent effects of sulpiride on EEG theta activity. Front Hum Neurosci 2013; 7:117.

Abstract
Dopaminergic drugs frequently produce paradoxical effects depending on baseline performance levels, genotype, or personality traits. The present study for the first time aimed to specify the mechanisms underlying such opposite effects using the following recently reported scenario as an example: depending on the personality trait agentic extraversion (agentic facet, aE; i.e., assertiveness, dominance, ambition, positive emotionality) the selective dopamine D2 receptor antagonist sulpiride (200 mg) had opposite effects on resting posterior vs. anterior theta activity in the electroencephalogram (EEG). In order to better describe these opposite pharmaco-EEG effects and to generate hypotheses regarding the underlying mechanisms, we measured the EEG intermittently over 5 h in 80 healthy male volunteers extremely high or low in aE who had received either placebo or one of three doses of sulpiride (50, 200, or 400 mg). The findings suggest a model postulating stronger pre- vs. postsynaptic subreceptor effects in high aE individuals compared to low aE individuals. Future studies may now systematically apply the model to other examples of paradoxical dopaminergic drug effects and examine the molecular basis of individual differences in pre- vs. postsynaptic dopamine D2 subreceptor sensitivities and densities.

Abstract
Task- and personality-related modulations of the N2 were probed within the framework of the revised Reinforcement Sensitivity Theory (RST). Using an appetitive choice task, we investigated 58 students with extreme scores on the behavioral inhibition system and behavioral approach system (BIS/BAS) scales. The baseline-to-peak N2 amplitude was sensitive to the strength of decision conflict and demonstrated RST-related personality differences. In addition to the baseline N2 amplitude, temporal PCA results suggested two N2 components accounting for a laterality effect and capturing different N2 patterns for BIS/BAS groups with increasing conflict level. Evidence for RST-related personality differences was obtained for baseline-to-peak N2 and tPCA components in the present task. The results support the RST prediction that BAS sensitivity modulates conflict processing and confirm the cognitive-motivational conflict concept of RST.

Abstract
A recent theory suggests that the agency facet of Extraversion (E) is based on brain dopamine (DA). The paucity of human data relevant to this model is probably due to the lack of widely accessible noninvasive psychophysiological indices and well-established behavioral measures sensitive to both E and manipulations of DA activity. Aiming to identify such measures, the authors assessed the electroencephalogram and n-back task performance in groups of introverts and extraverts after administration of either placebo or a selective DA D2 receptor antagonist. As predicted, the antagonist's effects on n-back reaction time measures and frontal versus parietal electroencephalogram theta activity were strongly and specifically modulated by E. New research avenues and theoretical extensions suggested by these results are discussed.

Evidence for a dopaminergic link between working memory and agentic extraversion: An analysis of load-related changes in EEG alpha 1 activity. Biol Psychol 2007; 74:46-59.

Abstract
Several lines of research point to the possibility of a partially overlapping dopaminergic foundation of the trait of agentic extraversion and individual differences in working memory functioning. This study investigates interactive effects of agentic extraversion and dopamine on spectral EEG measures of working memory. Using EEG activity in the alpha 1 band (8-10.25 Hz) as a dependent variable, we tested in a randomized double-blind design the effects of the D2-dopamine antagonist sulpiride during the performance of four load-graded n-back working memory tasks in participants high versus low in agentic extraversion. We expected extraversion-related differences in the load-responsivity pattern to be reversed by sulpiride, and the alpha 1 anterior-posterior difference actually depicted this reversal effect. However, in contrast to our expectations this effect was largely due to parietal instead of frontal sites.
